Title: Detection circuit for service interruption
Inventor: MATSUDA KENJI
IPC: G01R19/165
Filed: 1986-06-30
Abstract: PURPOSE:To improve holding ability by a large margin for service interruption of system by changing time constant of a detection circuit according to the state of a load current detected by a current transformer. CONSTITUTION:When the output of a comparator 1 is prescribed value which compares a full-wave rectified AC input with a reference voltage 5, a capacitor 3 is charged through resistances 2', 6 used for charging, and if the output of the capacitor 1 is other prescribed value, the charge of the capacitor 3 is discharged. WHen the voltage of the capacitor 3 is over the prescribed value, a timer 4 outputs a signal of detection for the service interruption. The state of a load current is detected by the current transformer 17 in a load current detecting circuit 19, then the output of said current is supplied to a base of a transistor 8 through an error amplifier 11 of the time constant control circuit 18. When the load current is large, continuity of the transistor 8 is large, but the resistance value for charging the capacitor 3 is small and the time constant of detecting circuit is small. On the contrary, when the load current is small, the time constant is large. The detection time for the service interruption is thereby changed by the extent of load constitution.

Title: Method and device for noise elimination
Inventor: IKEDA SHIGEJI
IPC: G10L21/0264
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for noise elimination in which the converging time is shortened and the distortion after the converging (a residual error) is reduced. SOLUTION: A signal to noise power ratio estimating circuit 10 operates an adaptive filter 12 which outputs pseudonoise signals from the reference noise signals of a reference signal input terminal 2, detects error signal power and pseudonoise signal power from the output pseudonoise signals of the filter 12 and outputs an estimated value SNR1 of the signal to noise power ratio based on these signals. Then, a comparison circuit 18 compares both estimated values of the input and the output of a delay circuit 17 and outputs the value, which is larger than the other, as an extended estimated value SNR3 . A step size outputting circuit 19 controls the step size of an adaptive filter 4 in accordance with the value SNR3 .  A subtractor 5 subtracts the pseudonoise signals generated by the filter 4 from the received signals, that are delayed by delaying circuits 3 and 8, and eliminates the background noise signal components in the received signals.

Title: Manufacture of semi-spherical grid
Inventor: OKUBO KAZUO
IPC: H01L21/66
Filed: 1987-06-19
Abstract: PURPOSE:To perform the correct potential measurement in a minor region by intermittently radiating and scanning an electron beam on the outer face of a semi-spherical metal substrate coated with a resist, depicting a grid pattern on the whole surface, and forming a semi-spherical grid with an electrodepositing means. CONSTITUTION:After a resist 6 is coated on the semi-sphere outer face of a semi-spherical metal substrate 4 at the uniform thickness, the semi-spherical metal substrate 4 is fitted to a motor drive unit 7, an electron beam or a laser beam is scanned on the surface of the resist 6 to intermittently radiate on a grid hole portion only, and a grid pattern is exposed on the surface of the resist 6. The resist 6 at the unexposed portion is then solved, and the grid pattern exposed with the surface of the semi-spherical metal substrate 4 is formed into a carved recess shape. After a stainless metal is precipitated only at the grid pattern portion in the developing process, it is removed from the semi-spherical metal substrate 4 to complete a semi-spherical grid. The semi- spherical grid allowing the correct potential measurement in a minor region is thereby obtained.

IPC: C01G19/02
Filed: 1983-08-25
Abstract: PURPOSE:To produce the titled fine powder of tin oxide having stable resistance, fine particle size and excellent dispersibility, by neutralizing an aqueous solution of a tetravalent tin salt with an alkali under specific condition, and calcining the resultant tin hydroxide powder under specific condition. CONSTITUTION:An aqueous solution of an alkali (>=10pH) maintained to >=65 deg.C is mixed with a solution of tin chloride (e.g. an aqueous solution of stannic chloride having a concentration of about 10-60%) to produce a precipitate (precipitation takes place when the pH of the mixture reaches about <=10). The mixture is added with additional tin chloride solution to adjust the final pH of the liquid to 5-1. The produced tin hydroxide powder is washed, dried, and calcined in a reducing atmosphere (or inert atmosphere) at 350-700 deg.C. The electrical resistance of the obtained tin oxide powder (as a compacted powder pressed under 100kg/cm<2>) is about 10<1>-10<5>OMEGAcm.

Filed: 1984-07-26
Abstract: PURPOSE:To form a net point-like latent image on a photosensitive substance without irradiating much light on an original at the exposure of the photosensitive substance and to form individual dot halftone-like latent images precisely with the size correspondng to the density of a picture to be reproduced by irradiating light reflected from the original on the charged photosensitive substance to form an electrostatic latent image and visualizing the latent image with toner. CONSTITUTION:When the photosensitive substance 11 is exposed to light passed through a filter 13 and the charge of a photosensitive substance part on an exposed bright part is discharged, a primary latent image is formed. The primary latent image arrives at a position opposed to a dot halftone formation device 14 in accordance wit the rotation of the photosensitive substance and converted into a secondary latent image, which is visualized with toner when passing the 1st developing device 15 containing cyan toner and then transferred to transfer paper 17. Then, a filter 13a is arranged on an optical path in accordance with the rotation of a filter device 10, the primary and secondary latent images of the same original are similarly formed on the surface of the photosensitive substance. These images are visualized when passing the 2nd developing device 15a and the visualized images are superposedly transferred to the same transfer paper 17. Thus, the visual image consisting of full colors corresponidng to the original picture is reproduced on the transfer paper 17 and then fixed by a fixing device.

Title: Numeric controller
Inventor: OKADA KIYOSHI
IPC: G05B19/404
Filed: 1980-10-31
Abstract: PURPOSE:To facilitate correcting operation by recognizing the corrected value of a feed speed by a numeric controller. CONSTITUTION:The output of a counter 21 for speed correction and that of a register 22 for data storage are sent to a multiplier 23, whose product V is sent as a speed corrected value to another multiplier 2. In an initial state, the register 22 has a 1 (100%), and the output of the multiplier 23 is determined by the value of the counter 21. The counter 21 goes up or down corresponding to a switch D or (u), thus varying the speed corrected value. With a speed recognition switch T, the counter 21 is set to a 1 and the value of the multiplier 23 is set in the register 22, so the corrected value is set without varying the value of the multiplier 23. To make further correction, the value of the counter 21 is increased or decreased.

As a result of it, the material plastic characteristic of the tip end part of the strip is changed B 1  → B 4  and thickness is changed H" → H accompanied by the above change. The more the rigidity is small the more the change of thickness becomes large and a few hundred mm of tip end part is rolled in wedge-shaped. Crease or flaw produced in the coil, is able to prevent by the above wedge.

IPC: H04B17/00
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To realize a function for measuring an output level of a television signal addition of only a small number of components. SOLUTION: When the mode of the device is switched to a measurement mode, an audio carrier signal in an intermediate frequency signal modulation section 19 is stopped, and a video signal is stopped and only a video carrier signal is outputted. Thus, a detection section 3 outputs a detected video carrier signal. An A/D converter 28 converts the video carrier signal into a signal, which is displayed on a display section 33. Since a CPU 29 controls the device in the measurement mode, a program for the measurement mode has only to be added to the device.
